Updating GDAL PostGIS Raster driver

Those past days, I’ve been working on the GDAL PostGIS Raster driver. I commited a version with relevant changes some days ago. It works with irregular blocking (tiles of different size), different pixel sizes in tiles and is pretty much faster than the previous version. Currently, I’m debugging to solve some errors, but I plan to have a stable version for next week. Of course, any feedback is welcome.
